Python to go
Python to goWeng Wei The author explains why they switched from primarily using Python to primarily using Go for serious projects. Some key reasons include that Go has better performance, code quality, testing, and concurrency features compared to Python. While Python is still good for hobby projects, Go enforces error handling, has built-in profiling tools, and makes deployment easier due to compiling to a single binary.

Playing with playgrounds
Playing with playgroundsEurico Doirado Playgrounds are interactive coding environments that allow developers to write Swift code and see the results immediately without running the project. Playgrounds come bundled with Xcode 6 and support Swift for both iOS and OSX development. Playgrounds provide features like a text editor, quick look previews of values, and value history to visualize how values change over time which make them useful for learning Swift. However, playgrounds can be slow and Xcode crashes sometimes since it was still in beta when the document was written.
Erlang: TL;DR
Erlang: TL;DRvorn Erlang is a functional programming language built for concurrency, distribution, and fault tolerance. It uses an immutable data structure and avoids loops with tail recursion. The OTP framework provides tools like supervision trees, behaviors, and hot code swapping. While Erlang syntax looks like Prolog, it can integrate with Ruby via bridges or messaging and runs on Heroku. The document recommends resources for learning Erlang and OTP and participating in the local Erlang meetup.
